I have no idea how to find it: involuntary sighing, but inhaling is in twos, as if broken in half.

That was an important question.
The less important one is WHO ARE YOU?
Homeopaths, homeopathists or homeopathicians?
I met with all of the above.

And for the dessert-Hahnemann: "When it is a question of the sacred art of curing, to neglect to learn is a crime"!

Mind; SIGHING

RESPIRATION; JERKING; inspiration; by two distinct efforts: acon., ang., ant-t., asar., led., tab.

or

RESPIRATION; INTERRUPTED; inspiration: Cina, led.

Since these are smaller sub-rubrics, you may want to consider the larger main rubrics as well. Good luck!

Hey, thanks David!
And I basically have given up on that one since meanwhile I found out more about this sighing and it seems now that there are two symptoms here:
one is involuntary sighing like a spasm of diaphragm with loud Ahhh inhale (and quiet exhale) and the other symptom is head pulsation which splits the inhale (if the inhaling takes longer it is fragmented into more than 2 (basically equal) parts.
So - I'm actually asking about TWO rubrics help here!
